Earthquake Swarm S20130120.1: Seismic Activity Near Mina, Nevada

An earthquake swarm designated S20130120.1 was recorded 27 km south-southeast of Mina, Nevada, between 15:13 UTC on 19 January 2013 and 10:12 UTC on 22 January 2013. Over 66 hours and 58 minutes, the sequence produced 65 earthquakes. Magnitudes ranged from 0.7 to 3.0, with the largest event occurring at 21:15 on 19 January. Focal depths were predominantly shallow, between 0 and 13 km, consistent with crustal faulting in the region.

The swarm exhibited typical characteristics of clustered seismicity, with an initial burst of activity on 19 January that included several events above magnitude 2.0, followed by a gradual decline over the subsequent days. Events were distributed across a compact area, reflecting localized stress release rather than a single mainshock-aftershock sequence. No damage or felt reports of significance were associated with the activity.

The Mina area lies within the western Basin and Range Province, a tectonically active extensional regime marked by north-trending normal faults and distributed shear. This setting forms part of the broader Walker Lane belt, where right-lateral strike-slip motion accommodates a portion of the Pacific-North America plate boundary strain. The Mina deflection, a prominent right-step in fault trends, concentrates seismicity and has hosted multiple historical earthquake sequences. Regional geology includes Quaternary alluvium overlying Mesozoic basement rocks intruded by Tertiary volcanics, with active faults capable of producing moderate-magnitude events.

Seismic swarms are recurrent in this portion of Nevada. Historical records indicate two such swarms since 1 January 2000, with the earlier episode occurring in 2003. These clusters underscore the importance of monitoring diffuse seismicity for understanding long-term strain accumulation along the Walker Lane.

Ongoing surveillance by regional networks continues to track background rates and any changes in activity patterns near Mina. Such data contribute to refined seismic hazard assessments for Mineral County and adjacent areas.
